ROAD-ROLLER.

Specification of Letters Patent.

Patented Nov. a, rate.

Application filed April 9, 1917. Serial No. 160,689.

To all whom it may concern:

Be it known that I, HENRY CULL, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and. State 01": Illinois, have invented certain new and useful Improvements in Road-Rollers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

In the ordinary type of road-rollers wherein a single cylindrical roller is used, or where a number of rollers are used, all mounted upon a single axle, unsatisfactory results have been obtained due to the fact that on roads under construction or repairs where materials have been deposited in small scattered heaps and left to be smoothed down or leveled by manual labor or spreaders, the lower portions of the material heaps are always packed or compressed, due to the (lumping process and the weight of the upper portions of the heaps, to a greater extent than the portions of the road between the heaps which have been filled by the spread ing process with loose materials. When the old type of road-rollers are run over the road, the roller or rollers only contact the lower already partly packed portions of the material heaps, thus still further compress ing or packing the same, but usually failing to contact or bear upon the loose material portions, thereby only partially rolling the road and leaving weak unpacked portions in the road which later on are the first to give way.

This invention relates to an improved form of. road-roller wherein a plurality of comparatively narrow roller wheels are arranged in staggered relation to one another, and each individually mounted and separately supported by an adjustably weighted frame, the inner end of which is pivotally connected to the fore-part or turn-table of the roadroller to permit each roller wheel to either raise or lower as the road-roller is drawn over a rough or unpacked road, so that all portions of the road will be packed or compressed uniformly, thereby showing up the portions requiring more filling in. and thus producing a roadbed which is solid and properly packed throughout.

It is an object of this invention to con struet an improved form of. road-roller portions 7 of a roadbed removably connected to a cart or propelling.

vehicle, and comprising a plurality of hingedly mounted supports of difierent lengths for packing rollers, each support provided with adjustably mounted weights to afford a meansof varying the pressure applied by said rollers.

It is an important object of this invention to provide a road-roller simple and of effective construction wherein a plurality of adjustable individually mounted staggeredweighted rollers are connected to a common propelling means, to afford ,ameans for uniformly packing all parts of an uneven roadbed.

ther and further important objects of the invention will be apparent from the disclosures in the drawings and specification.

The invention (in a preferred form) is illustrated in the drawings, and hereinafter more fully described.

On the drawings:

Figure 1 is a top plan view' of a roadroller embodying the principles of this invention.

Fig. 2 is a side view thereof with parts broken away.

Fig. 3 is a rear end view of the device.

Fig. 4 is a section taken on line 44, of Fig. 1.

F ig. 5 is a section taken on line 55 of Fig. 1. r

Fig. 6 is an end view thereof.

As shown'on the drawings:

The reference numeral 1, indicates the wheelsof a fore carriage, cart or vehicle, rotatably mounted upon the ends of 'an axle 2 supported by an axle bar 3, having centrallymounted thereon an anvil support 4, to which is secured by any suitable means ashaftor tongueito permit the cart to be attached to a motor vehicle or be drawn by horses as desired. Pivotally mounted. upon the anvil support 4, by means-of a kingbolt or pin 6, anda reinforcing plate or block 7, is a cross-beam or channel iron 8, to which said block 7 is'rigidly secured centrally therein between the front flange 9, and the rear flange 10, by rivets or any other suitable-means.

1A plurality of transversely adjustable hinges are disposed adjacent one another across the rear flange 10, of the channel iron 8, and each comprises an apertured yoked upper hinge member 11, having'an integral hook 12, thereon adapted to engage over the upper edge of the flange 10, to permit an integral apertured attaching flange 13, forming a part of said upper hinge member 11, to lie flat against the under surface of said channel iron 8, and be rigidly secured thereto by means; of screw bolts 14:, as clearly shown in Fig. 6. Pivotally connected to each of the upper hinge members 11, .by means of a pin-tlei 15, is a lower hinge member 16, having an apertured ear or lug 17 integrally formed centrally. on the upper surface thereof adapted to engage between the forks of said yoked upper hinge member to permit the pintle 1*5, to project through the apertured forks and through said apertured lug 17, to form a hinge. i

Rigidly but removably secured by means of a retainingbolt 18, in a suitable longitudinal T-shaped sloti19, formed in each of said lower hinge members 16, is arear- Wardly extending supporting I-beam 20.

The 'I-beams '20, are of different lengths,

preferably two, alternately arranged with respect to one another across the're'ar of the propelling cart, as clearly shown in Fig. 1. Adjustably. secured by means of bolts 21, to the outer or rear end of each of said supporting beams 20, and slidably engaging the upper flange thereof is a weight 22,

provided'w-ith' a longitudinal 'T-sloti23, in

the lower portion} thereof to permit said sliding engagement.

1 double armed or'yoked axle support :24, having an inverted T-slot'25', formed'inthe upper end thereof, is sli'dably engaged upon the outer or rear end of the lower flange of each I-beam 20, and removably secured in an adjusted posltionupon said lower flange by retaining bolts 26, which are threaded through the upper portion ofthe axle su-pportto grip or engage the lower I-beam flange. 'Integrally formed on the lower-"end of. eachof the forks or arms of t journaled astubaxle 28,- on which is keyed or otherwise secured between the a ms of each axle support '24, i'sa cylindrical hub or bear ng run 27, in each pair of'which is each axle support 24, a heavy roller or wheel- 29, the outer rim of which is com 4 With the road-roller parts arranged as.

shown and described a team of horses may be hitched to' the cart tongue 5, or said tongue may be attached to the rear of any suitable-type of motor vehicle to afford a means for drawing the road-roller over'an uneven roadbed 30 Asthe road-roller is propelled or drawn along the adjustable weights '22, secured in position upon the supporting I-beams .20,'together with the- Weights ofsai d I-beams'and the rollers 29, I

tendto force or press the respective staggered rollers 29, tightly down upon the roadbed, thus uniformly compressing" or packing all parts of said roadbed coming in contact with said adjustable road-roller.

With each of the rollers 29,.rota-tably -con-' nected to one of the hingedly mounted I beams 20, it willbe seen that an adjustable road-roller is produced which is adapted. to be drawn over anyuneven or rough roadbed and so adjust itself that the staggered V rollers 29, may either be raised or lowered autorn atically to conform to the surface over which they are'being drawn to compress or pack all parts of' the roadbed uniformly, and indicating which portions require additional filling in to make the entire roadbed of an even thickness and packed uniformly throughout, thus eliminating any weak spots in the roadbed, which usually occur when road-rollers .are used in which n the rollers are extremely, wlde and are mounted upon the same axle.

As clearly shown "n Figlv 1 of the draw 7 V ings, it will be noted that the roller car'- riage or' rear portion of the "road-roller 1S pivotally connected to the 'forejcarriagetby means ofthe kin'gbolt'6, thus permitting the" device to be turned as desired. It is also apparent that the fore carriage may be dispensed with andthat the kingbolt 6, may

be replaced by a suitable hook member to afford a means of connecting the roller por- 7 tion of the device to the "rear axle of any 7 suitable form of drawing vehicle." 7 It will; be noted that in order to" uniformly, pack all parts of'the roadbed" over V which the road-rollerv is drawn, it hasbeen found necessary, under 7 the construction shown, to arrange the rollers '29, in staggered relation tovon'ej another across-the de' vice. This arrangement is accomplished by providing the short and" long hingedly mounted supporting I-beams 20, or other suitable mounting means, which afford the supports for the rollers. It will of course be understood that the adjustable roller mechanism may be formed by arranging the road rollers closely adjacent one another across the device in a single row, or in any number of rows desired to accomplish'the purpose of uniformly packing a roadbed.

I am aware that variousother details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:
